Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the sauce into a custard-like emulsion that holds its body.
Melted butter
Adds richness and fat, and is emulsified into the yolks for a smooth texture.
Lemon juice
Adds acidity that brightens the rich butter and yolk flavour.

The step that matters

Blending in the melted butter. If the butter is added too fast or the mixture gets too hot, the yolks can scramble or the sauce can split. Adding the butter slowly over low heat while whisking keeps the yolks thickened and the emulsion smooth.

Swap the nutmeg

How well each one fits the dish's main ingredients (egg, butter, lemon, parsley, pepper):

  1. Tarragonfits better
  2. Thymefits better
  3. Marjoramfits better
  4. Nutmegthe original

Fit is the average pairing score against egg, butter, lemon, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
